Composite Actions on Github

Introduction

Most of the time when using workflows some steps are duplicated on other worflows.

When the time come to update those steps, we need to take care about all different aerea where steps has been duplicated.

It would be more convinient to have a common place where a single update can rule them all.

How can we organize this central place ?

Inside a github organisation, when you have multiple repositories and you want to share actions between all those repositories.

• Create a central repository
• Clone the repository
• Create the expected layout

mkdir -p .github/workflows/actions

• Move in this directory

cd .github/workflows/actions

For Each composite actions you want to create :

• Create a directory (this will be the name of the action)

mkdir mycoolaction

• Create an action.yml file inside this directory.
